IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 1 36,325, datedFebruary 25, 1:73.

To all whom it may concern:

Be it known that I, JOHN F. KINGWILL, of the city of Chicago, in thecounty of Cook and State of Illinois, have invented a certain new anduseful Improvement in'HarveStingMachines, of which the followingis afull description, reference being had to the accompanying drawing makinga partof this specification, in which- Figure 1 is a plan view, Fig. 2 afront elevation, and Figs. 3 and 4 enlarged details.

My device is shown applied to a Marsh harvester, in which the locationof the drivers seat, relative to the tongue, is such that it has beendifficult to arrange a lifting device by means of which the driver canconveniently elevate or depress the front of the platform which carriesthe sickle, as must he very frequently done; and the object of myinvention is to obviate this difficulty.

The frame-work of the machine is constructed in the ordinary manner.

Sis the drivers seat; T, the tongue, the rear of which is pivoted tosome part of the frame-work, so that when the tongue is ele vated thefront of the platform is depressed, and vice versa. a is a metal platesecured to the inside of the bar A, and has a series of notches, e, inthe front edge. b is a metal rod, one end of which is pivoted in theplate a and bar A, while the other end passes loosely through the bar B.c is an arm or lever permanently secured near the inner end of the rod1), and it has upon one side a projection, d, to engage with the notchesc. The center of b is enlarged, and between this point and the bar B isa spiral spring, 8, which holds the rod 1) and lever cin the positionshown in Fig. I

3. To the outer end of 'b is secured a lever, 9, arranged to be withinreach of the driver. h is a metal plate placed outside of the bar B.iisa projection on the inside of the lever g, so arranged as to be incontact with the face of the plate 72, and serves as a fulcrum for thelever y when used to withdraw the rod 1) and disengage the projection dfrom the notches e. f is a rod, the upper end of which is pivoted to theouter end of the arm a, and the other end is pivoted to the tongue T.

In use, the operator, by moving the top of the lever g from himlaterally, can disengage the projection d from the notches e, and then,by pulling this lever toward him, or pushing it from him, can raise orlower the tongue, and I with it the front edge of the platform, as maybe necessary. When the lever is released the action of the spring willengage the projection d with one of the notches c.

Any suitable spring may be used instead of the spiral spring shown, andit may be located in some other position.

My device can be used upon other agricultural implements, where it isnecessary to raise and lower some portion thereof.

What I claim as new is as follows:

The combination of the rack a, rigidly-attached arm 0, sliding rod 1),spring 8, and lever g, when applied substantially as and for thepurposes specified.
